EMIL STAHL, OF NEW YORK,'N. Yr

.,APPARATUS FOR CHARGING AND DRAWING CARBONATED BEVERAGES.

SPECIFICATION forming part of Letters Patent No. 523,872, dated July 31,1894. A plication filed December 5,1898. Serial ITO-492.833. (Nomo'del-lTo all whom it may concern.-

Be it known that I, EMIL STAHL, of'New York city, New York, haveinvented an Improved Apparatus for Charging and Drawing CarbonatedBeverages, of which the following is a specification.

This invention relates to an improved apparatus for charging and drawingcarbonated beverages and in which the fountain is connected to thecarbonator in such a manner, that the gas required for forcing thebeverage from the fountain into the dispensing apparatus is suppliedcontinuously from the carbonator, while heretofore such gas wascontained within the body of the fountain.

, The principal ad vantage resulting from my invention is that the waterneed not be carbonated under a surplus pressure, and as it will not loseany of its absorbed gas, it will retain a uniform pungency andeffervescence up to the very last.

In the accompanying drawings Figure 1 represents an elevation of myimproved apparatus. Fig. 2 is a longitudinal section of the faucet D,and Fig. 3 a cross section on line y, y, Fig. 2.

The letter A represents the carbonator being an apparatus forcarbonating water.

B represents the fountain containing the charged water, and O is thedispensing apparatus. a, is the water pipe that connects the carbonatorto the valve D of the fountain B.

b, is a pipe that connects the fountain to the dispensing apparatus 0,by a three way cock E, while 0, is a gas pipe that connects thecarbonator to the valve'D of fountain B.

The valve D is of the construction more fully shown in Figs. 2 and 3.The valve-head is threaded at its lower end and engages the tapped neckof vessel B. Through the valve head there extend two passages d, and e,of which the larger passage (:1, opens at the top into a cup d, that maybe closed by a screw cap 61 A vent (i in the cup permits the escape ofgas, when the screw cap is removed. The passage (1, is moreover providedwith a laterally extending branchd, which is controlled by a screw valvef, and which is adapted to connect with a lateral passage 9, extendingthrough a stud g. This stud is connected to the gaspipe c. The passagee,

is connected at its lower end with a siphon tube e, extending throughthe'fountain B, to a point near the bottom of the latter. At the top,the passage e, turns at right angles,

the lateral branch e being controlled bythe siphon 6', until thefountain is filled. During this operation any gas that may be containedwithin the fountain will flow into the carbonator through pipe 0.

After the fountain is charged, it is disconnected from the carbonator,shipped to its destination, connected to dispensing apparatus O by pipeI), and to a liquid carbonic acid tube by pipe 0. The water may now betapped in the usual manner, after the cock E has been turned to connectthe fountain with the dispensing apparatus. sary pressure for drawingoff the water will be supplied from the carbonator or liquid carbonicacid tube through pipe 0, that delivers the gas through passages g, (1and d, to the surface of the liquid contained within the fountain. Asthe level of this liquid sinks, the volume of gas contained within thevessel will be proportionately replenished and thus a uniform pressurewill at all times be maintained. The cup (1, serves to fill salts orflavoring extracts directly into the fountain.

What I claim is v The combination of a vessel B with a valve D, havingpassages d, (Z and 6, e a cup d, connected to passage d, a pair of screwvalves f, h, and a pair of perforated studs 9 'i', that communicate withpassages (1 e substantially as specified.
